When a chimaeric soybean leghaemoglobin gene was introduced into the genome of another legume species, Lotus corniculatus, nodule-specific expression of the chimaeric gene was found in root nodules formed on fully regenerated plants inoculated with the Lotus microsymbiont, Rhizobium loti. Expression under control of the 5′ upstream region of the soybean gene was regulated at the level of RNA and followed the correct developmental timing. This indicates a conserved induction mechanism for leghaemoglobin genes in legumes.
